Periods of ammonium nitrate application during the cultivation of soft winter wheat variety Krasa Dona in the southern part of the Rostov region

open access: yesАграрная наука Евро-Северо-Востока, 2020
The studies were carried out in the southern part of the Rostov region in 2017-2019 on typical carbonate chernozem. Studied was the efficiency of periods of ammonium nitrate application (N30, N30+30 ) in autumn when the vegetation season is finished, in ...

INFLUENCE OF SOIL TYPE AND NITROGEN FERTILIZATION SUGAR BEET YIELD AND QUALITY [PDF]

open access: yesPoljoprivreda, 2011
In 2009 and 2010 we studied effect of nitrogen fertilization on the yield values on two soil types of different physical and chemical properties. Nitrogen was applied in autumn as a pre-sowing treatment on the basis of Nmin supplies in the soil, and as a

Potato Yield Gaps in North Korea and Strategies to Close the Gaps

open access: yesAgronomy, 2020
Potato has become one of the staple crops to improve food security in North Korea since the late 1990s. However, the potato yield has been stagnated around 11–12 t ha−1 for several decades, and a food shortage is still a primary issue in North Korea ...

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.

Comparison of Five Nitrogen Dressing Methods to Optimize Rice Growth

open access: yesPlant Production Science, 2014
The applicability of five nitrogen (N) dressing methods to rice cultivation was examined using the canopy spectrum-based nitrogen optimization algorithm (CSNOA), leaf area index (LAI), site-specific N management (SSNM), N nutrition index (NNI), and N ...

Increasing paddy yields and improving farm management: results from participatory experiments with good agricultural practices (GAP) in Tanzania [PDF]

open access: yes, 2018
Rice is an increasingly important commodity in sub-Saharan Africa. In Tanzania, the rice yield gap is as high as 87%, due to a combination of production constraints and sub-optimal crop management.

Nitrogen top-dressing fertilization of maize cultivated in single and twin-row systems1

open access: yes, 2021
The aim of this study was to evaluate the effects of cropping systems (single and twin-rows) and N fertilizer rates in the second top-dressing on the agronomic performance and relative economic returns of maize. The experiment was conducted in a randomized block design, with subplots and three repetitions.

The value of mid-season top-dressings of nitrogen fertilizer for main-crop potatoes [PDF]

open access: yesThe Journal of Agricultural Science, 1957
Twenty-one field experiments were carried out from 1953 to 1955 on main-crop potatoes to compare dressings of nitrogen applied wholly to the seedbed (as ammonium sulphate), with equivalent dressings applied partly to the seedbed (as ammonium sulphate) and partly as a top-dressing (of ‘Nitro-Chalk’) just before the final ridges were set up.
